Hello. I can help you. Assuming that all three switches used to work and now you have this problem, you have a switch that is worn out or has a wire that has come loose. Turn off the power to this fan and open up one switch at a time. look for a disconnected wire, or a loose wire. If the wires were pushed into the clip on the switch check carefully as these little clips often fail after a while. I seriously think you will find a loose wire and that will solve your problem, once you reconnect it. If that is not the case, you will have to replace one switch at a time until you have replaced the bad one. I recommend that you make a diagram of each switch once you have it out in the open noting which color of wire goes to each screw or spot. You will always have one screw on a switch which is a slightly different color from the rest. Always note which color wire goes to the odd color screw and make sure you always hook that wire to the odd color screw in the new switch.
